The photos are made at night (moon icon) using different sky textures (added in bold) with the option "Enhance external brightness" checked.They illustrate the changes in version 1.1 of the PhotoVideoRendering plug-in.

Sorry if i misunderstand, but do you mean you are solely using light generated in the programme by the texture used by the sky?Enhance external brightness.... did this not disappear with the beta test plug in.Probably me being a thicko, but i really would like to understand this better, at the moment the only thing i do to improve image quality is increase pixals to 2 or 3 thou.thx in advance Enkonyito
